Two line-transect estimators for population density of flushing animals, based on elliptic flushing curves, have recently been proposed, one by Burnham (1979, Biometrics 35, 587-595) and one by de ...

The density of Brazilian tapirs (Tapirus terrestris) was studied in the northeastern part of the Pantanal wetlands of Brazil using two simultaneous and independent methods: (1) systematic camera ...

This technique has long been at the forefront of quantitative ecology, epidemiology and the social sciences for estimating the size of populations that are difficult to count directly. By using ...

After the government and settlers drove them to near extinction in the West, the U.S. government reintroduced wolves to Idaho and Yellowstone National Park in 1995 and 1996. (File photo courtesy of ...

The new method estimated 1,150 wolves, while the trail cam method estimated 840 wolves, Roberts said. Even though it has been a year since Idaho Fish and Game officials announced their new estimation ...

“Although no population estimation technique is perfect, we now have an independent source of information that validates the camera-based estimates that we’ve been using to guide wolf management since ...
